In just a couple weeks more, Gossip Girl fans can go back in time to witness Lily van der Woodsen during her younger years. As reported previously, the May 11 episode of Gossip Girl will take the form of a prequel, laying the groundwork for a spin-off that could start as soon as the fall. So far, we already know that Brittany Snow (American Dreams, Nip/Tuck) will be playing the younger Lily, while Krysten Ritter (Veronica Mars, Breaking Bad, ‘Til Death) has been cast for the part of Lily's troubled older sister, Carol. Moreover, Jericho's Shilo Fernandez has also signed on to play Owen, a brooding valley punk.

But that's not all. According to Entertainment Weekly, executive producer Josh Schwartz and co-creator Stephanie Savage are contemplating on the idea that Lily may have crossed paths with characters from their previous hit, The O.C., which ended its run on FOX in 2007.

Not all titles featured on BuddyTV are available through Amazon Prime.

In line with that, Schwartz and Savage are toying with the notion of having Lily interact with earlier versions of some of The O.C.'s most notable characters including Kirsten Nichol, Jimmy Cooper and possibly a young Julie Cooper, who was previously played by Melinda Clarke.

The O.C. became an instant teen favorite when it premiered on the FOX Network in August 2003. The show popularized its setting, Orange County, and led to shows like MTV's reality series Laguna Beach: The Real Orange County and the Bravo documentary series The Real Housewives of Orange County.

While there might be some familiar faces on the spin-off, Schwartz reveals that there won't be any from Gossip Girl so fans of Lily and Rufus shouldn't expect the rockstar dad to show up.

"It's not the story of how Lily met Rufus," executive producer Josh Schwartz explained.
